  2. Prevents Radiant Heat Transfer
  3. Stops Air Transfer
  4. Installs Easily
  5. Deadens Sound of Rain and Hail
  6. Doesn't Promote Nesting of Rodents, bugs and birds

  8. Stops Ice Dams and Condensation

1. R-value Not Affected by Humidity

The R-value of Prodex Total - A reflective insulation is not affected by humidity! It is the measurement of the system rather than a measurement of just the product. Measuring the R-value of the system (a real-world application) is a truer measurement vs. a measurement of the product only. Click for real-world test parameters (technical brochure). For example, what good is the posted R-value of fiberglass given that once installed in an environment that includes any moisture it loses R-value? Virtually all real-world environments include some humidity. Unlike fiberglass the R-value of Prodex Total is NOT affected by humidity. 

Traditional insulation types such as cellulose, fiberglass and rock wool lose R-value when exposed to humidity. There is ALWAYS humidity in a house.

2. Prevents Radiant Heat Transfer

Prodex Total prevents radiant heat transfer - The primary source of heat-flow.

Ever wonder why it's so hot and humid upstairs in your house in the summer? Roof materials exaggerate the heat of the summer and frigid temperatures of the winter. Metal is a very good conductor of heat and cold. In hot weather, metal sheeting rapidly radiates the sun's heat into a house. In cold weather it rapidly releases the heat out of your house.

Prodex reflects 97% of the radiant energy (primary source of heat flow) that strikes it. Prodex also reflects back the heat inside your home. Each unit of radiant heat energy that is reflected away from your home in the summer, and each unit that is reflected back during the winter, means less operation of your heating and air conditioning system - Less wear and tear on your equipment - Less money you pay in utility costs.

3. Stops Air Transfer

Prodex Total is an air barrier. Air-flow carries moisture that impacts the temperature and integrity of the building. Air-flow affects a house's behavior in a fire (spread of toxic smoke and gasses). Air barriers also separate garages from conditioned spaces. In this case an air barrier would also serve as a "gas barrier" an obvious safety feature. 

4. Installs Easily

Prodex Total is light, flexible and installs easily. It's a lot easier and less expensive to install a thin eco friendly product than a bulky product that requires a mask, gloves and ventilation. Pinching 6 inches fiberglass between the framing and sheeting is not easy. Installing insulation

5. Deadens Sound of Rain and Hail

Prodex Total reduces the sound of rain and hail. If you live in an area with heavy rains you can't even hear your favorite shown during a rain storm if you're under an unprotected roof.

6. Doesn't Support the Nesting of Rodents, bugs and birds

Prodex Total does not provide for the nesting of rodents, bugs and birds. Rodents, bugs and birds aren't able to digest the foil.

7. Doesn't Support Mold and Mildew

Prodex Total is good for your health! It's resistant to the following fungi: Aspergillus niger, Aspergillus avus, Aspergillus versicolor, Penicillium funiculosum and Chaetomium globosumniger.

8. Stops Ice Dams and Condensation

Temperature differences between the inside and outside of a house can create condensation. The condensation that forms under roofing can make it seem like it's raining inside in the summer and frosting in the winter.

Prodex eliminates the moisture (condensation) from forming on the sheathing. It does this by making the temperature of the inside of the sheathing approximately the same as the outside. When the heat or cold from outside comes through the sheathing it hits the outside reinforced foil of Prodex and is reflected back upwards through the underside of the sheathing. This process keeps the sheathing temperature consistent on both sides. In addition, the inside layer of the reinforced foil in Prodex reflects away the heat (heater) or cold (air-conditioning) from inside the house from getting to the sheathing. This also helps in preventing condensation. Learn more about roof insulation.

Prodex partnered with Insulation4Less to develop Total Plus - Designed specifically for the U.S. and Canada - Higher R, Stonger and Safer. See Technical sheets: 10M5MWhite

Comparing House Insulation - Rigid Board, Spray Foam, Fiberglass and Cellulose to Prodex Total

Rigid Board Is Rigid!

Because it's inflexible, it does a poor job filling the gaps or cracks that may exist in your walls. As a result, you'll have air passage ways in and out of your home. Air traveling in and out will bring moisture with it. This can lead to a multitude of problems such as mold, mildew and rot. It also doesn't prevent radiant heat transfer.

Spray Foam Insulation Won't Stop Radiant Heat Transfer

In addition to being very expensive, spray foam insulation won't prevent radiant heat transfer (the primary source of heat-flow in and out of your house). Without a radiant barrier, when your roof gets hot it radiates solar-generated heat down. This often results in it being hotter in your house than out. It's also suggested that you supplement open cell foam with a vapor barrier. Why not get the vapor barrier all in one product?

Fiberglass R-value In A Lab

You need an insulation that doesn't lose its thermal protection when you need it most - In the humidity of a winter. Fiberglass and cellulose R-value tests are done with the parameters of no humidity and no air. Maybe that exists somewhere in the universe, but not in your house. Fiberglass loses R-value once damp - It will get damp due to normal humidity levels. Once fiberglass gets damp, it will stay damp. Not only will you have trapped moisture in the blanket causing rot and mold, the damp blanket will provide less and less R value as the moisture builds. 

For those of you the like to get into the weeds, I'll explain in more depth why fiberglass loses R-value once wet.

Fiberglass insulation is composed of woven fiber stands. The fiber strands contain hundreds of small air pockets. The air pockets provide the insulation. Once exposed to moisture, the air pockets fill up with water (rather than air) and the insulation loses the ability to provide R-value. 

Moisture build-up between fiberglas and the exterior of your home cannot evaporate. Warnings on the insulation rolls advise you to completely protect yourself from coming in contact with fiberglass. Batts do not seal walls, ceilings and crawlspaces tightly.

Couple this with the fact that fiberglass insulation does not prevent radiant heat transfer (primary source of heat flow) and you can see why fiberglass insulation is not the recommended as a stand-alone insulation for house. Compare R-values of fiberglass to reflective insulation.

Wet Cellulose Insulation

Moisture absorption makes it heavier, causing it to lose R-value. It is prone to create too much dust that is blown into the house through small cracks or holes around fixtures. Like fiberglass, it can be a health problem.

Dear Insulation4Less,
My contractor had never done IR barrier before. By the end of the job, they were standing in the house to get out of the heat. "It's COOL in here. I Like this stuff." was their comment

These photos are just a gift to you.... We have used your brilliant material in this historical home and in the homes of many of our family members.... if a couple of 75 year olds can do it, anyone can...
